Question

In the figure below, a small block is sent through point
Awith a speed of 6.2 m/s. Its path iswithout friction
until it reaches the section of length L= 12 m, where the
coefficient of kinetic friction is 0.70. Theindicated heights are
h1 = 6.6 m and h2 = 1.5
m.

(a) What is the speed of the block at point B?
1
m/s

(b) What is the speed of the block at point C?
2 m/s

(c) Does the block reach point D?
3 (yes or no)

If so, what is its speed there and if not, how far through
thesection of friction does it travel?
4 in units
of5 (m/s or m)
